Just spent 7 hours working on both my fronts. Drivers side hub bolts broke free fairly "easily" but fought with the hub being seized onto the knuckle for an hour or two. Even with a hub puller, I ended up resorting to smacking the ever living shite out of it with a chisel.
Passenger side, spent way too much time trying to get the rotor off without destroying it. 10mm bolts stripped immediately trying to pop it off. THEN, I only got 1 hub bolt off. The other 3 are seized something fierce. Let PB soak for an hour or two, wire brushed what I could of the ends sticking through, even heated with a torch. Not a budge. Coming back today with a more diesel impact gun and hope the PB worked its magic.
The problem is the working space for those bolts. Can't get a breaker on them cause of the wheel well and the axle is in the way as well!
Definitely budget a good chunk of time for this if your car has some good mileage on it. Mine has 221k.
